HEATING DEVICE.

Application filed July 29, 1921.

To all 10720222. it may concern:

Be it known that l, Roennr V. VVIEDER- wax. a citizen of the United States, residing at Atlantic City, in the county of Atlantic and State or New Jersey, have invented certain new and useful Improvements in Heating Devices, of which the following is a specification.

Th s invention relates to water heaters, and more particularly to devices for heating the circulating water in cooling systems of motor vehicles, and is an improvement over the construction shown in my oopending application, Serial No. 32,795, filed December 23, 1920.

In the said application, I have disclosed and claimed a water heater comprising a casing arranged in front of the radiator, a casing arranged in the rear of the radiator, and burner casings arranged at each side of said front casing.

in the present invention, 1 provide front and rear casings adapted to be arranged on opposite sides of a radiator, and a pair of burner casings arranged at each side of the front casing, the front casing being provided with a central air passage separating the burners from each other.

An object of the present invention is to provide means to prevent explosions caused lay accumulations of explosive vapors collecting under the hood of the vehicle and passing to the burners.

A. further object is the provision of means for supplying the proper amount 01 air to support combustion when. the vehicle is running or standing still.

further object of the invention is the provision ot means for feeding air to each of the burners independently of the other and prevent setting up of cross currents causing irregular feed, to the burners.

in the accompanying drawings, 1 have shown one einhodiment of the invention. In this showing:

Figure 1 is a trout elevation of a motor vehicle showing the invention applied,

Figure 2 is a perspective view of the burner casings,

Figure 3 is a rear elevation of the front casing removed,

Figure 4 is a perspective View of the front casing with the front plate removed,

Serial No. 488,443.

The invention comprises a front casing 5, and a rear casin 6, adaptec to he secured in position by means of bolts The bolts are provided with enlarged ends or heads 8 and are adapted to he passed through openings in the rear wall oi the front casing. The opposite ends of the bolts are threaded for the reception of nuts 9, whereby the device is secured in position.

Referring to Figures 3 to 6 01" the rawings, the tront casing comprises a front plate or wall 10 and a rear wall 11. connected at opposite ends by side walls 12. The

bottom of the casing is open and the casing is provided with an inclined top 12, the rear oit' which is adapted to be arranged against the rz-idiator. As shown, the rear wall is depressed, as at 13, forming relatively shallow central section. The upper portions of the end sections are separated from the central section by means of trans verse walls 1 which terminate above the bottom of the casing and are connected to horizontal walls 15. The horizontal walls form supports for substantially rectangular sections 16 in which the burner casings are adapted to he inserted.

The horizontal walls are provided with openings for the passage ot the burners and are further provided with pertorat ions 17 arranged beneath the burners Reiierring to Figure 2 of the drawings, the burner casings 18 are formed integrahheing connected by a fuel container 19 substan tially equal in thickness to the reduced central portion of the front casing. Burners 20 are arranged in the burner casing, the burners being controlled by suitable control members 21. A filling opening 22 is provided on one end of the burner casing. The I burner casing is provided with a double lower wall 23, adapted to be arranged on the outside of the walls of the front casing when assembled (see Figure 3).

The rectangular sections 16 are provided with clips or brackets 24 arranged on the front and adjacent the bottom adapted to support a sheet 25 of asbestos or similar material insulating the front wall 10 of the easing from the rectangular sections. The front and side walls of the rectangular sec tions are provided with openings 26 for the passage of air. As shown, the side walls of the rectangular sections are spaced from the side walls 12 of the casing and from the walls 14 to provide air spaces 27. The rear wall 11 of the front casing is cut-away at each side adjacent the top forming openings 28 through which the products of combustion from the burners pass to the radiator. Adjacent the rectangular sections, the rear wall extends upwardly, as at 29, and is provided with a plurality of perforations 30. Openings 31 are arranged in the front wall of the casing to permit lighting the burners, inspecting, etc. These openings are normally closed by covers 32, hinged to the easing, as at 33, and retained in closed position by a resilient catch 34. As shown, the covers may be provided with transparent windows 35. The side walls of the front casing are provided with slots 36 for the passage of the burner controlling handles 21. Suitable clips 37 are arranged on the side of the easing, the clips being provided with lower offset ends 38 adapted to engage beneath the burner casing to retain it in position.

The depressed portion 13 of the rear wall forms, in efiect, two separate passages 39 and 40, arranged between the front and rear wall of the casing and between the rear wall and the radiator respectively. A dividing plate 41 extends vertically through the passage 39 to a point beneath the normal position of the burners dividing it in two sections and preventing cross currents of air in the passage 39 whereby the supply of air to the two burners is maintained uniform and variations in burning are prevented. A sleeve 42 is supported by the vertical wall 41, the sleeve extending through the walls of the casing and permitting the usual hand crank of the engine to pass through the casing. The front wall is provided with two sets of perforations 43 arranged on opposite sides of the vertical wall 41 for the purpose of supplying air to the burners when the vehicle is running. A deflector plate 44 is arranged in the rear of these openings and is adapted to deliver the air downwardly. The upper portion of the passage 40 is provided -with a horizontal perforated wall 45 and with a vertical perforated wall 46 extending from the horizontal wall to the top of the casing. The burner casing is provided with an upwardly extending rib 47 adapted to be received in the vertical wall 41. The rear casing comprises a rear wall 48, side walls 49, and top and bottom walls 50. The front ofthe rear casing, or the side adjacent the radiator is open throughout the greater portion of the casing but is closed by a wall or plate 51 adjacent the top. The walls 48 and 50 are provided with relatively large openings 52 adjacent each end, and relatively small openings 53 adjacent the center.

Arranged in the fuel tank beneath each of the burners, there is provided a packing 54 of wool or similar material which is adapted to prevent the liquid fuel from passing to the burner in excessive quantities due to splashing when the vehicle is passing over uneven ground.

The operation of the device is as follows:

When the vehicle is standing, air enters the back of the front casing through the perforated plate 46 and passes through an opening 55 formed between the upper edge of the rear wall and the top of the casing. Air flows through the passage 39 beneath the horizontal wall 15 and through the openings 17 to the burners. The products of combustion pass upwardly through the rectangular sections 16 and through openings 28, thence the tubes of the radiator and through the openings 52 of the rear casing.

WVhen the vehicle is moving, air is supplied to the burners through the openings 43. The deflector plate 44 causes the air to flow downwardly and prevents it from passing through the opening 55 and through the radiator. The vertical wall 41 prevents cross currents of air from being set up in the passage 39 and insures an equal distribution of air to the two burners. The provision of the dividing wall 41 further permits the use of a single burner if desired. When a single burner is used, the dividing wall prevents a current of air from passing downwardly through the unused burner to the used burner.

The air spaces 27 arranged on the side of each burner serve as equalizers. ,With the vehicle running, or standing still, a sudden rush of air against the rear of the front casing is prevented from passing to the bur ner and extinguishing the flame by the extended portion 29 of the wall. A portion of the air under such conditions passes through the perforations 30 and to the top of the burner, but the larger portion of the air follows the path of least resistance through the passages 27 and the openings 26, thus equalizing the'portion of the air passing to the top of the burner and preventing the flame from being extinguished.

The provision of the perforated walls 45 and 46 in the upper portion of the passage 40 forms a chamber in. which explosions or burning of gasoline vapor, which may find its way into the heater are localized. Any gasoline vapors entering the. heater casing, would enter the passage from the bottom where the heater is slightly spaced from the radiator and if ignited, the explosion or burning would be localized in this passage by the walls and and the flames prevented from passing through the radiator to the vicinity of the engine. The central openings 53 in the rear rasing permit pas sage of air through the radiator to the passage 40 and thence upwardly through the openings to the passage 39. Normally, no appreciable amount of air passes through these openings but it a. body or" air suddenly flows against the rear casing. and av portion of it passes through the openings 52 against the [low of the products of combustion tending to extinguish the flame, this is oii set and equalized by an additional supply of air passing through the openings 53 and thus crating a slightly greater flow oi air and products of combustion in the normal direction.

Normally, a portion of the products of combustion pass between the walls 48 and 51, and out through the openings 53 inv the rear wall 48, thus spreading the heat dis tributed to the entire radiator.

It is to be understood that the form of my invention herewith. shown and describet is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resort d to without departing from the spirit of the invention or the scope of the subjoined claims.
